KNOCKDOWN SCREEN-DOOR OR WINDOW-FRAME.

SPECIFICATION forming part of Letters Patent No. 355,969, dated January 11,1887.

Application tiled July 31, 1886. Serial No. 209,628.

To @ZZ whom it may concern,.-

Be it known that I, JOHN W. BoUGHToN, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Knockdown Screen-Doors or Window-Frames, which improvement is fully set forth in the following specification and accompanying drawings, in Which- Figure l represents a front view of ascreendoor embodying my invention. Fig. 2 represents a vertical section thereof in line x w, Fig. l, on an enlarged scale. Fig. 8 represents a horizontal section inline y y, Fig. l, on an enlarged scale. Fig. LIrepresents a perspective View of a screen-frame embodying my invention.

Similar letters of reference indicate corresponding parts in the several gures.

My invention consists of improvements in the class of knockdown insect-screens embodying doors and window-frames, the construction whereof is such that the screens are adapted to be reduced in size according to the dimensions of doors and windows.

Referring to the drawings, A, Figs. l, 2, and 3, represents a screendoor consisting of the top rail, B, bottom rail, C, intermediate rail, D, and side st-iles, E F. Each rail has its ends formed with tenons G H, the tenons G being adapted to be fitted in mortises G of the hanging stile E, and the tenons H in the mortises of the opposite or locking stile, F. Each rail is formed with kerfs J, which extend into the rail from the inner terminations of the tenons H, forming tongues K. The rails are made of such length that when the door1 is set up it is slightly wider than the door-frame; hence, in order to makeaproper iit, the rails require shortening, to accomplish which the ends ci the tongues K are cut oi the required extent, thus lengthening the tenons H, said tenons then being inserted in the mortises of the stile F, and the latter properly driven up, so that the desired width of the door -is attained. The ends of the tenons H which project outside of the stile F are now cut of, the rails and stiles being secured together in any desired manner. The netting may then be attached to the door as formed,

side stiles.

the hinges, and knob and lock, if any, having been previously or being subsequently secured to the saine, and thus the screen-dooris ready for use.

It is evident that in setting up the door, should the door-frame be found of much less width than the door, or the latter is intended to be employed for a narrower door-frame, the size of the door may be adjusted by reducing the length of the tongues K,as has been hereinbefore described.

Either mortise for the top or bottoni rail is vertically extended, as seen in Fig. 2, so that the top rail may be moved down or the bottom rail moved up. By this provision the height of the door may be reduced,or the door adjusted inv height, according to requirements, in which case the'ends of the stiles beyond the rails are cut oft'. In lieu of extending the mortises, I may make a number of disconnected mortises, in either of which the tenons'may be fitted; but when I use an extended mortise the unoccupied space is properly plugged or filled in, so that no gap is presented in the If desired, the top and bottom rails may be reversed,as the tenons of the same are out of center, and thus provision is made for reducing the height of the door.

Fig. 4 shows a window-screen or insect-frame constructed similar to the door, excepting that the rail D is omitted,as not requisite,said frame being adjustable in width and height, according to requirements of the Window frame or sash.

It will be seen that I provide convenient means for adjusting knockdown doors and frames, the parts whereof, in their normal condition, being readily packed or formed into t handles convenient for handling, transporta- IOO K, in combination with the side stile having extended vertical mortises, al1 as described, mortisestherein,allsubstantially as described. whereby the said frame may be readily ad- 3.
